AUTOMATICWATERy CONTROL.

appnation ined september 2 1, i925, serial, '$7,724.

To al! fwhom t may coaocmf Be it known that we,4 MARvrn l-IAGEYV and Lonen' T.' MCKEE, citizens of the United Statesand residents of Los Angeles, in the oo ,iuityof Los Angeles and Stateof California, have invented new and useful 'lm proyements in AutomaticWater Controls, whichthe following is a specification.

vThisinvention relates to ahydraulically actuated device for automatically and intermittently operating mechanisms such as flush valves. `It is .,especially 'serviceable in connection 'with flushing "devices for toilets and urinals wherein it visdesired yto effect intermittent flush. f It V`isV `he primaryobject of this invention to provide a mechanism which ycomprises a reciprocatingmotor element wherein an operatingmember is slowly moved toward the outer yend lof its stroke by the `flow of fluid into itschamber; and, at the outerend of its stroke, a relief is actuated to cause discharge of fluid from the chamber,v whereupon the cycle is repeated. In addition to the broader objects of -this invention there are certain details of design, whereby an economical, simple, durable and compact structure s obtained. 'Y A 'lfhese'objects together with other objects andfcorresponding accomplishments are ob,- Atained bymeans of thegembodiment ofour invention illustrated in the accompanying drawings in which: i

Figfl is a section through a flush valve having our improved operating mechanism connected thereto; andFig'. 2fis a section as seen'on"tl1e"l'ine2-'2 of. Figfl.

Referring vmore particularly tothe drawings, kthe bod of a iush valve commonly known as a ushometer is indicated by The 'body is, provided with an inlet chambertfrom which extends an inlet'V adapted to'be'connected to the supply service pipes. The up )er portion of the body has a cylindrical rim 6 which is externally threaded, and is provided with a passage orv duct 7 leading upwardly through the wall. -vAit the opposite side is an extension 8 having a passage 0r duct 9 leading therethrough. The passage 9 extends upwardly through the wall of the rim 6 and at the extension 8 is rovided with al checkvalve 10 for controlling the flow. Upstandingk in the body at the central portion thereof is a tubular seat 11 communicating with a discharge outlet 12 adapted to berconnectedu to piping legirling.to"thebdevicetov be iushed. The

bodyis;.s,o...arranged that liquid may enter the inlet side..and 'ina orderv to pass outwardly must pass over the upper portion of the tubular seat 11l andl downwardly through the outlet 12.

Mounted.

,n the rim 6 and secured there` tofby l threads is a cap ljhaving a Harige 14E a'rrange,d' to cooperate with ,the upper portion -of rim, 6 and clamp therebetween a flexible diaph-ragm'l preferably formed of rubber.Y The diaphragm has aV port lG'at the .center .thereof which registers lwith the port in the tubularseat 11. 4 There is an annular passage 17 i in thecap communicating, with the f space above the diaphragm Athrough vports 18 arranged to 'registen with the ducts and 9 so that V'there Ais a duct placing 'theportion of the structure above the diaphragm in communication witlithe portion below the diaphragm, .theduet being small. Likewise the duct 9 communicates with the 'space above the diaphragm. Secured'to the diaphragm at the port therein is a tubulanmember 19,"there being sufcient clearance between the internal wallY of the tubular port and themember 19 to permit the flow of water therebetween. In ordery to guidefthe tubefthe tube 19, there. are fins 20 i provided. The upper end offt'ubey 19 serves seatlfora valve discv 21having a stem 22depending'therefrom @11d extending belovthe/bottom of tube 191v This structure provides a"tilting valve. Formed on the side ofthe bodyis an extension 23 in'which isfslidablymounted la stem 24 arranged toV be registered withv4 the stem"2 2. 'There' ,isa compression spring 25v surrounding the Vstem v2t'an'd arranged to engage ahead' 26 thereby tending toholdthe 'stem 24 in its outer Vpositionfand away from4 stem`22. -Upon .pr'essinglthe head26,y the stem' 251; will' be c'a'usedwto engage the stem 22`^and `tilt`the valve disc 21 on its seat, thereby lifting the latter. The structure just described'is well known in thevart and forms no part of our present invention.

. Our invention Vrelates* to the means for tilting the stem 22. Secured to theextension 23 is a cylindrical housing 27 having a head 28 provided with a discharge chamber V29. The discharge chamber is connected by a tube `BOto extension 8 so asfto communicate with duct V9. An inlet is provided'in the head 28 anda tube 31 connected thereto. A fitting 32 connects'tube 31 and a tube 33 nu UU which leads to the inlet of the fiush valve. Fitting 32 contains a needle valve 34 for controlling the How of liquid in the tubes 33 and 31 to the head. ldounted Within the housing 27 and secured to the head is a sylphon 235 arranged so thatV when it is expanded it will engage the head 26 and move stein 2e. ln retracted position or when collapsed which is the normal position of 1 J- the sylphon, the latter is out of engagement with head 2G and the stem is permitted to remain in position such that the valve disc 21 may scat.

The device operates in the following manner: Water enters the valve through inlet and passes upwardly through duct 7 and passage 1T to the space above diaphragm 15. While disc 21 is seated, the liquid is within a closed relief chamber, forcing diaphragm downwardly so that it seats upon tubular seat 11 and closes the passage for water to the outlet. Water from the inlet also passes through tube 33, past valve 84 and through tube 31 to the sylphon. The escape of water from the sylphon is prevented, as tube communicates with the relief chamber above diaphragm 15. The sylphon is then caused to expand, eventually engaging the head 26 and stem 24 and moving the latter inwardly. Stem 24 engages stem 22 and unseats the valve 21, opening the relief chamber to the discharge. Water then discharges from the relief chamber, and the pressure of the water below diaphragm 15 causes the latter to raise from seat 11 and open the inlet 5 to the discharge outlet 12, permitting the free passage of water. Upon the relief chamber being open to the discharge, the sylphon is relieved of its pressure, being in Communication therewith, and immediately contracts allowing stem 2st to be retracted. Valve 21 then rights itself and seats. l/Vater begins to slowly enter the relief chamber through duct 7 and passage 17, moving the diaphragm 15 downwardly until it eventually seats on tubular seat 11 and closes the discharge ports stopping the flowV of water. The outflow of water from the sylphon is also stopped, and water enters the latter from the inlet through tubes 33 and 31,'

again expanding the sylphon and eventually tripping the relief valve, whereupon the operation is again performed.

Uur invention resides in the tripping mechanism, which may be applied to any flush valve or to other devices. The sylphon and associated parts form a device hereinafter broadly referred to as a motor.

What we claim is:

1. A device of the character described adapted to be connected to a hydraulically actuated iush valve having a relief chamber and mechanically operated means t0 release liuid therefrom so as to operate said valve including a slidable actuating stem, said device comprising an expansible chamber motor, a fluid inlet for said motor connected to the inlet of said valve and arranged to permit the passage of fluid slowly to said motor, said motor having a fluid outlet connected to said relief chamber, said stem being disposed to be engaged and opcrated at an end of the travel of the motor.

A device o1' the character described comprising a sylphon motor having a fluid inlet connected to a source of fluid supply under pressure, a needle valve arranged to control the passage of fluid through said inlet, said motor having a luid outlet, relief means for said outlet including an actuating stem, a check valve for preventing the back flow of liquid through said outlet, said stem being disposed in the path of travel of said motor so as to be operated thereby.

8. The combination with a flush valve having a relief chamber, a relief tilting valve and a slidable stem for actuating said valve of a control device comprising an expansible chamber motor having a constricted fluid inlet connected to the source of fluid supply under pressure arranged to permit the passage of fluid slowly, said motor being provided with a fluid outlet connected to said relief chamber, said stem being' disposed to be engaged and operated by the motor at the end of its travel.

In witness that we claim the foregoing we have hereunto subscribed our names this 9th day of September, 1925.
